Automatic brake device for baby stroller

Abstract

Automatic brake devices for a baby stroller are independently arranged on the left side and the right side of the rear end of the trolley respectively; each independent brake device comprises a movable sleeve, a fixed sleeve, a wheel seat, a butt clamp, a compression spring, a brake shaft and a brake line; the brake lines and the brake shafts between adjacent brake teeth of wheels are lifted by a pushing force applied on handles by a trolley puller so as to enable the brake shafts to be pulled out of parts between the adjacent brake teeth of the wheels to realize brake and unlocking; and when the manual pushing force on the handles is withdrawn, the tension of springs in the wheel seats pushes the brake shafts to enter parts between the adjacent brake teeth of the wheels quickly so as to realize brake. The automatic brake devices improve the personnel safety factor of a baby in the trolley and improve the convenience in use of the trolley.

Description

technical field [0001] The invention relates to the field of infant vehicles, in particular to an automatic braking system for infant strollers. Background technique [0002] The wheels of baby strollers in the current market can be roughly divided into two categories: universal wheels and ordinary wheels. The universal wheels can be braked and unlocked by operating the wrench on them; Refers to: Each rear leg tube of the baby car corresponds to a wheel seat, each wheel seat has a cavity, the lower end of the rear leg tube is inserted into the cavity of the wheel seat, the wheel seat is traversed by the central axis of the wheel, and the brake handle is located between the two wheels. When the brake pads on the side of the brake handle are embedded between the adjacent brake teeth of the wheel, the brake is realized (6-8 pieces of brake teeth spread out from the center of the wheel near the side of the foot pipe, and the clip between the adjacent brake teeth The angles are...

AI Technical Summary

Problems solved by technology

[0003] It can be seen from the above that when the baby stroller wants to stop and walk after stopping, its semi-automatic braking device needs to be manually operated, which means it is more troublesome.

In addition, when a careless mother chats, makes a phone call, or needs to leave immediately in an emergency, she may forget to position the baby stroller and brake, thereby causing potential safety hazards for infants and young children, such as the baby stroller sliding along the slope and causing serious consequences See related incident report)
